HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 64, 309, 158 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 64, 309, 158 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 64, 309, 158 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 64, 309, 158 is 1.
HCF(64, 309, 158) = 1
HCF of 64, 309, 158 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 64, 309, 158 is 1.
Highest Common Factor of 64,309,158 is 1
Step 1: Since 309 > 64, we apply the division lemma to 309 and 64, to get
309 = 64 x 4 + 53
Step 2: Since the reminder 64 ≠ 0, we apply division lemma to 53 and 64, to get
64 = 53 x 1 + 11
Step 3: We consider the new divisor 53 and the new remainder 11, and apply the division lemma to get
53 = 11 x 4 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 64 and 309 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(53,11) = HCF(64,53) = HCF(309,64) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 158 > 1, we apply the division lemma to 158 and 1, to get
158 = 1 x 158 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 158 is 1
Notice that 1 = HCF(158,1) .
